Bar/Quill Capability on Horizontal Machining Center
HPN800 can be equipped with BAR/QUILL and spindle core cooling system. The new BAR design brings improvement in performance and accuracy compared to traditional horizontal boring mills.
- Center-Mounted Spindle Eliminates the column twist by side-mounted spindle
- Ergonomically Superior A full enclosure, with ATC and APC are standard to maximize the performance
- Center Thru Coolant Better cutting performance, longer tool life, superior chip removal
Hybrid structure that achieves high productivity
The machine's structure, which combines high productivity with heavy-duty cutting capabilities, significantly improves the productivity of boring operations.
3-point support
High precision and rigidity are achieved through 3-point support and 5-point auxiliary leveling.
Fast forward speed: 60 m/min
This machine boasts top-level rapid traverse speeds for its size, resulting in exceptional productivity.
Honeycomb rib structure
The T-shaped, high-rigidity base features a honeycomb-type rib structure that provides high cutting performance.
End plate for injection molding machine
Because the end plates of injection molding machines are large and require high precision, high mechanical rigidity is essential. Furthermore, the burden of setup changes becomes greater with large workpieces.
The BAR series' high rigidity machine structure and BAR spindle enable deep hole drilling in a single chucking without setup changes, achieving both high-precision machining and productivity.
